required 450 feet of sewer line to be replaced at its Laguna
Hills, Ca facility where their jet fuel testing lab is located.
The sewer line was underneath the giant facility, included
a 90° turn and ran directly under the test lab. It was
clearly stipulated that the lab itself could not be disturbed
as would be the case with traditional line replacement technique.
Huffer
Plumbing, of Orange, California, had bought a tool from a
Trenchless America competitor. After two solid weeks on the
job, and after two machine break-downs, they had progressed
a mere 150' when the head punched out of the pipe and another
pit needed to be dug despite the additional structural disruption
it caused. It was a Wednesday, and Huffer picked up the phone
and called Trenchless America.
We
arrived with a machine by noon Thursday and 24 hours later,
using three working pits to accommodate the 90° direction
change, all 250' of new sewer line was fully installed.
With
those results in hand, Huffer called the competitor and instructed
them to come pick up their machine, and bought the Trenchless
America system on the spot!
